Photomontages are a lot of fun to create. Just let your imagination run wild, anything goes !
Here is a scene taken in Newfoundland to which I added photos of my cat's red ball creating a weird, but interesting image.
A couple more Newfoundland photos with the red spheres added.
This is a great way to experiment with Photoshop, you can come up with some very creative images with very simple objects. The computer is the perfect medium for this kind of experimentation.
